To ell-whom '55 concern: I

Be it known that K, JAMES H. SAGER, a citizen of the United States, and resident of Rochester, iii-the county of Monroe and The present ins 'ention relates to bumpers for automobiles, and more particularly to the connection between the supporting err; thereof and the vehicle imme bar, an object of this invention being to pro ide a construction in which the supporting arms may be connected to the frame bars without any perforation of the letter, and notwithstandthe provision on one side of the frame bars of splash guards, or other devices, which would prevent the fastening means about the frame bars. hese and other ends, the invention "s of certain parts and. combinations is all which will be her .insfter (i6: scribed, the novei features being pointed out in the appended claims.

Entire drewingsz- 'iiigure i is a side View or" the forward end vehicle frame bar, showing the imeonnection between the letter and the bumper supporting arm;

' i a plan View the construction 1: section on the line ii-25, Fi

is a perspective View of the adjustebroping member.

Referring more pe cuiarly to thedrswings, 1 ind ietes the forward curved end of thechanneicd frame bur oi a vehicle, and 2 the bumper her which is supported near 0; ends by supporting arms, only one ()i 1, 11 L in this instance, guided on on inner member own Eech supporting arm, in comprises an outer member 3" with a coiled spring 5 interposed between them, and permitting the yielding of the bumper bar 2 in :1 known manner. The inner end of the supporting arm prei erebiy has an enlargement 6, with one face thereof out-curved and provided w teeth. 7. This out-curved, enlarged porn is received within an in- 2:. block 9, the well of the pool? ided with teeth for 'ient be e1 i, so as to preeeiicn of rtion curved poetic-s The in the poi erin to it vided in order that the supporting arms of.

the bumper bar 2 may be maintained horizontel, notwithstanding the curves of the forward ends of the vehicle frame bars 1 As is apparent, this block may be shifted along the frame bar 1 until it assumes the desired position thereon, "after which the supporting arm may be turned to a horizontal position. So far as certain features of this invention are concerned, the block 9 is not necessary thereto.

To the end of clamping each supporting in this instance, concentric with the curved toothed portion, so that the bolt acts as a pivot on which the bumper supporting arm may be swung. A Washer 13 on the end of the bolt serves to hold the-bolt to the bumper supporting arm. The other or upright arm of the L-shaped bolt 11 is pro vided ith a screw-threaded portion 14 on which a nut 15 turns. On this upright arm of the boit 11, above the nut, is guided a clamping member 16 for cooperation with the under side or the channel bar 1. This clamping member 16 has an extension 17 for cooperating with thc bolt above the channel bar 1, so that a wide bearing on the bolt is obtained .to prevent any twisting action of the clamping member of the clip. It is pre ferred that the shorter and upper arm of the bolt 11 shall have its longitudinal axis converge with reference to the longitudinal axis of the member 16, as by tl is arrangement greater pressure is provi led on thechennel bar 1 at the upper edges of the flanges of the channel bar, so that there is a tendency to force the edges of the chennel I bsr toward eechother, and in this way pre ventthe Withdrawal of the bumper supporting arm.

To still further prevent the withdrawal of the bumper supporting arm, the clamping member 16 carries two devices which air A e the lower flan e of the channel bar 1. 5 g e ihese devices are, in this instance, in the rams bar 1, a clip 11 may be form of hook bolts 18 engaging over the lower flange of the channel bar, and extending under the latter, and through two perforated lugs 19 on the clamping member 16, these bolts being provided with nuts 20 by which they may be firmly drawn into en gagement with the channel bar 1.

By the foregoing construction it will be seen that the bumper supporting arm is secured to the channel bar from one side of the latter only, thus leaving the other side free for the provision of a splash guard, mud guard, or other device which would utilize such a space. The cl amping .means acts on the channel bar in a manner to exert greater pressure on the channel bar near the free edges of the flanges, thus tending to contract or compress the channel bar at this point, making it difficult to withdraw the bumper arm laterally from the channel bar 1, This lateral withdrawal is further prevented by two hooltcd bolts carried by the adjustable clamping member of the clip, and engaging the lower flange of the channel bar.

l/Vhat I claim as my invention and desire to secure by Letters Patent is:

1. The combination with a channeled frame bar opening horizontally and a bumper supporting arm, of means for securing the arm to the frame bar comprising a fastening bolt connected to the bumper supporting arm to hold the latter on the upper side of the frame bar and lying on a vertical side of the frame bar, and means adjustable on said bolt and carrying a hooked device for engaging about the lower flange of the frame bar.

2. The combination with a channeled frame bar opening horizontally and a bumper supporting arm, of means for securing the arm to the frame bar comprising a fas tening bolt connected to the bumper su 'iporting arm to hold the latter on the upper side ofthe frame bar, a clamping member ad justable on the bolt to engage the under side of the frame bar, and a hook carried by said clamping member for engaging about the lower flange of the frame bar.

The combination with a channeled frame bar opening horizontally and a bumper supporting arm, of means for securing the arm of the frame bar comprising a fastening bolt engaging the supporting arm and lying on one side of the frame bar to hold the supporting arm on the upper side of the frame bar, a clamping member adjustable on the bolt, and a hook adjustable on the clamping member and engaging the lower flange of a frame bar.

4.. In combination with a channeled frame her opening horizontally with bumper supporting arm, means for securing the arm to the channeled frame bar comprising an L-shaped fastening bolt having one arm thereof engaging the bumper supporting arm to hold the latter to the vehicle frame bar, and the other arm lying on a vertical side of the frame bar, and a clamping member guided on the vertical frame of the bolt, the longitudinal axis of the clamping member, and the longitudinal axis of the arm of the bolt which engages the bumper supporting arm. converging with referencec to each other, so as to produce a greater compression action on the frame bar near the free edges of the flanges of said bar.

A support fbr buffer bars of automobiles comprising a supporting arm having an end formed with a toothed out-curved portion, and also with an opening substantially concentric with said toothed outcurved portion, a block adapted to restupon the vehicle frame and formed with a toothed iii-curved portion receiving the out-curved portion of the supporting arm, an L-shaped fastening bolt having one arm passed through the opening of the supporting arm, and a clamping member adjustable on the other arm and engaging the vehicle frame to hold the block to the frame and the supporting arm to the block.

(3. In combination with a vehicle frame, a bumper supporting arm, and a block interposed betwecn the arm and the frame to permit the arm to swing on the block to assume a horizontal position, means for securing the arm of the vehicle comprising an l.-shaped'fastening bolt having one arm passed through said bumper supporting arm, and a clamping member adjustable on the other arm of the bolt to engage the frame to hold the block to the frame and the supporting arm to the block 7. In combination with a channeled frame bar opening horizontally and a bumper supporting arm, means for securing the arm to the vehicle comprising an L-shaped fastening bolthaving one arm thereof engaging the bumper supporting arm, a clamping member adjustable on the other arm of the bolt, and a hooked bolt carried by said clamping member and engaging the lower.

boltand engaging the lower flange ofthe vehicle frame bar.
